Pseudo-bond graph model for the analysis of the thermal behavior of buildings

Abstract : In this work, a simplified graphical modeling tool, which in some extent can be considered in halfway between detailed physical and data driven dynamic models, has been developed. This model is based on Bond Graphs approach. This approach has the potential to display explicitly the nature of power in a building system, such as a phenomenon of storage, processing, and dissipating energy such as heating, ventilation , and airconditioning systems. This paper represents the developed models of two transient heat conduction problems corresponding to the most practical cases in building envelope, such as the heat transfer through vertical walls, roofs, and slabs. The validation procedure consists of comparing the results obtained with this model with analytical solution. It has shown very good agreement between measured data and Bond Graphs model simulation. The Bond Graphs technique is then used to model the building dynamic thermal behavior over a single zone building structure and compared with a set of experimental data. An evaluation of indoor temperature was carried out in order to check our Bond Graphs model.
